DogeCV

A easy to use computer vision library used for FTC Games to detect game objects. Based on Ender CV and OpenCV.

DISCLAIMER

THIS REPO IS STILL UNDER HEAVY DEVELOPMENT. I WILL BE ADDING FURTHER DOCUMENTATION, BUG FIXES AND NEW DETECTORS SOON. MANY OF THE

However, although many of the detectors are currently pretty basic, I am putting alot of time in effort into this lib, and open sourced it to let the community work or learn from my mistakes. This is the exact code my team will be running so I do have a decent motivation to work on it ;)

FAQ

• If I use dogeCV can I still use Vuforia?

  Yes, but not at the same time. You must disable Vuforia before using dogeCV and vice versa. Also, the default vuforia localizer doesn't detach from the camera by default. In order to make it detech from the camera, you must use another vuforia localizer.
